Description

[Technical Field]

[0001] The present invention relates to a piping material holder. [Background technology]

[0002] For example, piping material laid in an attic space so that its length extends horizontally is suspended from the ceiling while being held by a plurality of piping material holders. The piping material holders are suspended by fixing the piping material holders to suspension bolts fixed to the ceiling or by fixing the piping material holders directly to the ceiling.

[0003] Furthermore, some piping materials have a pipe body covered with a low-strength covering material such as a thermal insulating material. When the piping material is supported from below by a piping material holder, the weight of the piping material concentrates at the portion of the covering material supported by the piping material holder. To prevent the covering material from collapsing due to this concentrated load, it has been proposed to support the piping material with a long, curved member, such as the auxiliary member for a hanging hardware disclosed in Patent Document 1. The auxiliary member for a hanging hardware is supported by a band portion of the hanging hardware and is used by being interposed between the piping material and the band portion. Compared to the band portion, the auxiliary member for a hanging hardware is a long plate-like member that is longer in the longitudinal direction of the piping material. Therefore, compared to when the piping material is supported only by the band portion, the weight of the piping material can be distributed and supported. This reduces the collapse of the covering portion of the piping material compared to when the piping material is supported only by the band portion. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-133430 Summary of the Invention [Problem to be solved by the invention]

[0005] However, when the hanging hardware auxiliary member disclosed in Patent Document 1 is used, the hanging hardware auxiliary member extending from the band may sag as it extends from the band. In this case, even when the hanging hardware auxiliary member is used, the piping material is supported locally by the band, so the load concentrated on the covering material becomes too large and the covering material is crushed. [Means for solving the problem]

[0006] A piping material holder for solving the above-mentioned problems is a piping material holder having a fixing part fixed to a structure, and a holding part integral with the fixing part, the holding part surrounding the piping material, the piping material having a pipe body covered with a covering material that can be compressed and deformed in the thickness direction, from the outer periphery of the covering material, the holding part being a plate part that forms at least a part of the part surrounding the piping material, the plate part extending in the longitudinal direction of the piping material and being deformable in the circumferential direction of the covering material in a width direction perpendicular to the extending direction of the plate part. The gist of the present invention is that the plate portion has a plate portion, a fastening band portion extending in a band shape in the width direction from the plate portion and forming part of the portion surrounding the piping material, and a retaining portion which is integrated with the fixing portion and arranged in a position aligned with the fastening band portion in the width direction, and which engages with the fastening band portion when the piping material is surrounded by the retaining portion, thereby maintaining the state in which the piping material is surrounded by the retaining portion, and that multiple sets of the fastening band portion and the retaining portion which engages with the fastening band portion are provided in the extension direction.

[0007] In a piping material holder, among the edge portions of the plate portion extending in the extension direction, the extending edge portion of the fastening band portion may have a slit formed thereon that is located between adjacent fastening band portions in the extension direction and extends in a direction intersecting the extension direction.

[0008] With regard to the piping material holder, the fastening belt portion has a plurality of belt portion engaging portions arranged side by side in the direction of extension from the plate portion, and the maintaining portion has a maintaining portion main body that defines the internal space through which the fastening belt portion passes, and a maintaining portion engaging portion that is provided on the maintaining portion main body and engages with the belt portion engaging portion, and the maintaining portion engaging portion may be positionable in a position that allows the fastening belt portion inserted into the internal space to move in a direction that narrows the enclosed space surrounding the piping material, and may also be positionable in a position that restricts movement in a direction that widens the enclosed space by engaging with the belt portion engaging portion. [Effects of the Invention]

[0009] The present invention can suppress the crushing of the covering material. [Brief explanation of the drawings]

[0011] Hereinafter, one embodiment of a piping material holder will be described with reference to FIGS. <Piping materials> As shown in Fig. 2, the piping material 10 has a pipe body 11 whose outer surface is covered with a covering material 12 that is compressible and deformable in the thickness direction. The pipe body 11 is made of resin or metal. The covering material 12 is formed into a cylindrical shape from a low-strength material such as urethane foam insulation.

[0012] <Piping material holder> 1 and 2, the piping material holder 20 has a fixing portion 30 and a holding portion 40 that is integral with the fixing portion 30. The piping material holder 20 holds the piping material 10 that has been laid so that its longitudinal axis extends horizontally, while supporting it from below. The piping material holder 20 is fixed to a suspension bolt 13 that serves as a structure that extends downward from a ceiling surface (not shown). The piping material holder 20 is made of a deformable resin such as polypropylene or polyacetal.

[0013] <Fixed part> As shown in FIGS. 1 and 3, the fixing part 30 has a cylindrical fixing part main body 31 and a pair of extension parts 36 extending from the fixing part main body 31.

[0014] The fixing portion body 31 has the suspension bolt 13 inserted therethrough and is fixed to the suspension bolt 13. The fixing portion body 31 has a pair of opposing wall portions 311, and a first connecting wall portion 32a, a second connecting wall portion 32b, a third connecting wall portion 32c, a fourth connecting wall portion 32d, and a nut receiving portion 32e that are installed between the opposing surfaces of the pair of wall portions 311. The direction in which the longitudinal sides of the wall portions 311 extend is the axial direction X of the fixing portion 30. The piping material holder 20 is used with the axial direction X coinciding with the up-down direction. The axis L of the fixing portion body 31 extends in the axial direction X.

[0015] As shown in Figures 1 and 10, each wall portion 311 is in the shape of a rectangular plate. Each of the first to third connecting wall portions 32a to 32c has a wall thickness in the axial direction X and has an arc-shaped inner peripheral edge when viewed in the wall thickness direction. The fourth connecting wall portion 32d is disk-shaped. Each of the first to third connecting wall portions 32a to 32c is mounted on the pair of wall portions 311 at one end side in the short side direction of the wall portion 311, and the nut receiving portion 32e is mounted on the pair of wall portions 311 at the other end side in the short side direction of the wall portion 311.

[0016] The first to third connecting wall portions 32a to 32c and the nut receiving portion 32e each have an arcuate inner peripheral edge that faces the axis L of the fixing portion main body 31. The first connecting wall portion 32a is bridged between the pair of wall portions 311 at first ends of the wall portions 311 in the axial direction X. The second connecting wall portion 32b is spaced apart from the first connecting wall portion 32a toward the second end in the axial direction X.

[0017] The nut receiving portion 32e is bridged between the pair of wall portions 311 and between the first connecting wall portion 32a and the second connecting wall portion 32b in the axial direction X. The nut receiving portion 32e closes the space defined by the pair of wall portions 311, the first connecting wall portion 32a, and the second connecting wall portion 32b from one side in a direction perpendicular to the axial direction X. The fixing portion main body 31 is provided with a nut press-in inlet 33 defined by the pair of wall portions 311, the first connecting wall portion 32a, the second connecting wall portion 32b, and the nut receiving portion 32e. The nut press-in inlet 33 opens from the other side in a direction perpendicular to the axial direction X.

[0018] The third connecting wall portion 32c is spaced apart from the second connecting wall portion 32b toward the second end portion in the axial direction X. The space defined by the pair of walls 311, the second connecting wall portion 32b, and the third connecting wall portion 32c is open between the pair of walls 311 in a direction perpendicular to the axial direction X.

[0019] The fourth connecting wall portion 32d is bridged between the pair of walls 311 at second ends of the walls 311 and is spaced apart from the third connecting wall portion 32c toward the second end in the axial direction X. A space defined by the pair of walls 311, the third connecting wall portion 32c, and the fourth connecting wall portion 32d is open between the pair of walls 311 in a direction perpendicular to the axial direction X.

[0020] The fixing portion main body 31 has a shaft hole 30a defined therethrough in the axial direction X. In a plan view of the fixing portion main body 31 seen from the first end side in the axial direction X, the shaft hole 30a is defined between the inner peripheral edges of the first connecting wall portion 32a to the third connecting wall portion 32c, the inner peripheral edge of the nut receiving portion 32e, and the opposing surfaces of the pair of wall portions 311.

[0021] As shown in FIG. 3, the hexagonal nut 14 is press-fitted into the nut press-in port 33. Of the opposing surfaces of the pair of wall portions 311, the portions that define the nut press-in port 33 face each other across the axis L. The shortest distance between the opposing surfaces of the pair of wall portions 311 is slightly larger than the dimension between the two parallel surfaces of the hexagonal nut 14. The hexagonal nut 14 press-fitted into the nut press-in port 33 is held between the pair of wall portions 311. In addition, the nut receiving portion 32e restricts movement of the hexagonal nut 14 toward the side opposite the opening of the nut press-in port 33. The central axis of the hexagonal nut 14 coincides with the axis L of the fixing portion main body 31, and the female threaded hole of the hexagonal nut 14 communicates with the axial hole 30a.

[0022] 2, the suspension bolt 13 is inserted into the axial hole 30a from the first end side of the fixing portion main body 31. The suspension bolt 13 inserted into the axial hole 30a is screwed into the hexagonal nut 14, thereby fixing the fixing portion 30 to the suspension bolt 13.

[0023] As shown in FIG. 3 , in the fixed portion main body 31, the extension direction Y is the direction of a straight line connecting the opposing surfaces of the pair of wall portions 311 at the shortest distance. The pair of extension portions 36 extend from both side surfaces of the fixed portion main body 31 in the extension direction Y. The pair of extension portions 36 extend from both sides of the fixed portion main body 31. Each extension portion 36 has a first plate portion 36a extending in the extension direction Y like an elongated plate, and a second plate portion 36b spaced apart from the first plate portion 36a in the axial direction X and extending obliquely relative to the first plate portion 36a. The first plate portion 36a and the second plate portion 36b face each other with one side in the plate thickness direction. The second plate portion 36b is inclined relative to the first plate portion 36a so as to approach the first plate portion 36a as it moves away from the fixed portion main body 31 in the extension direction Y. Therefore, the distance between the first plate portion 36a and the second plate portion 36b in the axial direction X decreases as the distance from the fixed portion main body 31 increases in the extension direction Y.

[0024] <Holding part> 1, the holding portion 40 is integral with the fixing portion 30 and holds the piping material 10, which is made by covering a pipe body 11 with a covering material 12 that is compressible and deformable in the thickness direction, in a state in which it surrounds the outer periphery of the covering material 12. The holding portion 40 also has a maintaining portion 41 that is integral with the fixing portion 30, a connecting belt portion 51 that is integral with the maintaining portion 41, a plate portion 61 that is integral with the connecting belt portion 51, and a fastening belt portion 71 that is integral with the plate portion 61. The direction perpendicular to the axial direction X and the extension direction Y of the fixing portion main body 31 is defined as the thickness direction Z of the piping material holder 20.

[0025] <Maintenance Department> 3 and 4, the retaining portions 41 are integrated with each of the extending portions 36 extending from the fixing portion main body 31 in the extending direction Y. Therefore, the pair of retaining portions 41 are provided on both sides of the fixing portion 30 in the extending direction Y. Therefore, the pair of retaining portions 41 are provided at two locations spaced apart in the extending direction Y.

[0026] Each retaining portion 41 has a retaining portion main body 42 that defines an internal space S, and a locking portion 43 provided on the retaining portion main body 42. The retaining portion main body 42 has a rectangular tubular shape that is open at both ends in the thickness direction Z. The retaining portion main body 42 has a first end face 421 on one of its end faces in the thickness direction Z, and a second end face 422 on the other end.

[0027] An internal space S is defined inside the maintaining unit main body 42. A first end surface 421 and a second end surface 422 surround the opening of the internal space S. The maintaining unit main body 42 has, among the inner surfaces defining the internal space S, a pair of first demarcating surfaces 41a facing in the axial direction X and a pair of second demarcating surfaces 41b facing in the extension direction Y. A first opening width W1, which is the distance between the pair of first demarcating surfaces 41a, is smaller than a second opening width W2, which is the distance between the pair of second demarcating surfaces 41b.

[0028] 4, the locking portion 43 is integrally molded with the upper first demarcation surface 41a, which is one of the pair of first demarcation surfaces 41a. The locking portion 43 has a thin, long plate shape as a whole. The locking portion 43 has a tilting base 44 integral with the upper first demarcation surface 41a, an operating piece 45 extending in a strip shape from the tilting base 44 so as to pass through the internal space S, and a retaining portion engaging portion 46 protruding from one longitudinal surface of the operating piece 45.

[0029] The tilting base 44 protrudes from the upper first demarcating surface 41a toward the lower first demarcating surface 41a. The tilting base 44 is provided on the first demarcating surface 41a closer to the first end surface 421 than the center position in the thickness direction Z. The tilting base 44 has a dimension in the extension direction Y. The operating piece 45 extends longitudinally in the thickness direction Z from the tilting base 44. The side of the operating piece 45 opposite the tilting base 44 side in the longitudinal direction protrudes from the second end surface 422 to the outside of the maintaining unit main body 42. The locking unit 43 can be operated by operating the part of the operating piece 45 that protrudes from the maintaining unit main body 42.

[0030] The operating piece 45, excluding the tilting base 44, is spaced downward from the upper first demarcating surface 41a. The operating piece 45 has a first thick surface 45a and a second thick surface 45b that are opposite to each other. The first thick surface 45a of the operating piece 45 faces the upper first demarcating surface 41a inside the maintenance unit main body 42, and the second thick surface 45b faces the lower first demarcating surface 41a inside the maintenance unit main body 42. A gap exists between the first thick surface 45a and the upper first demarcating surface 41a. By utilizing this gap, the operating piece 45 can be operated to move the first thick surface 45a closer to the upper first demarcating surface 41a. This operation causes the operating piece 45 to tilt around the tilting base 44 as a base point.

[0031] The retaining unit engaging portion 46 protrudes from the second plate thickness surface 45b of the operating piece 45 toward the lower first demarcating surface 41a. The retaining unit engaging portion 46 is provided in the longitudinal direction of the operating piece 45, near the second end surface 422 of the retaining unit main body 42. The retaining unit engaging portion 46 extends over the entire operating piece 45 in the lateral direction.

[0032] The retaining unit engaging portion 46 has an engaging surface 46a that is substantially perpendicular to the second thickness surface 45b, and an inclined surface 46b that is inclined more than the engaging surface 46a. The inclined surface 46b is inclined in the thickness direction Z so as to approach the second thickness surface 45b from the second end surface 422 toward the first end surface 421 of the retaining unit main body 42.

[0033] When the operating piece 45 is not operated, the opening width between the retaining unit engaging portion 46 and the lower first demarcating surface 41 a is the minimum opening width. When the operating piece 45 is operated and the first plate thickness surface 45 a is brought close to the upper first demarcating surface 41 a, the opening width between the retaining unit engaging portion 46 and the lower first demarcating surface 41 a is the maximum opening width.

[0034] <Connecting belt part> 1 and 3, the connecting band portion 51 connects the support portion 41 and the plate portion 61. Therefore, the holding portion 40 has the connecting band portion 51 that connects the support portion 41 and the plate portion 61. The connecting band portion 51 extends in a band shape from the second end surface 422 of the support portion main body 42. In a side view of the connecting band portion 51 in the extension direction Y, the connecting band portion 51 curves in an arc downward as it moves away from the second end surface 422. The connecting band portion 51 has a first band surface 51a that is continuous with the lower surface of the support portion main body 42, and a second band surface 51b that is continuous with the second end surface 422 of the support portion main body 42.

[0035] A first end of each connecting belt portion 51 is connected to the retaining portion 41 by the retaining portion main body 42, and a second end of each connecting belt portion 51 is connected to the plate portion 61. The connecting belt portion 51 has an expanded portion 53 midway in the direction of extension from the retaining portion main body 42. The expanded portion 53 is formed by expanding a portion of the connecting belt portion 51 in the lateral direction of the connecting belt portion 51. An inlet 54 is formed in the expanded portion 53 of the connecting belt portion 51. The inlet 54 opens on both the first belt surface 51a and the second belt surface 51b. The inlet 54 has a rectangular shape with its longitudinal axis extending in the lateral direction of the connecting belt portion 51. The opening width of the inlet 54 in the lateral direction is smaller than the opening width of the inlet 54 in the longitudinal direction.

[0036] <Plate section> As shown in FIG. 1, the plate portion 61 has a rectangular shape when viewed in the thickness direction Z. The direction in which the longer sides of the plate portion 61 extend is the extension direction F. The extension direction F coincides with the extension direction Y. The direction in which the shorter sides of the plate portion 61 extend is the width direction V. The extension direction F and the width direction V are perpendicular to each other. Since the plate portion 61 is made of resin, the plate portion 61 can be deformed in the width direction V. Specifically, the plate portion 61 can be deformed into an arc shape along the circumferential direction of the covering material 12 of the piping material 10. The plate portion 61 can also be deformed into various curvatures depending on the outer diameter of the piping material 10.

[0037] The plate portion 61 has edges extending in the extension direction F at both ends in the width direction V. Two connecting bands 51 extend from one of the pair of edges, a first edge 611, and two fastening bands 71 ​​(described later) extend from the other, a second edge 612. The two connecting bands 51 and the two fastening bands 71 ​​are arranged with a gap between them in the extension direction F of the plate portion 61. The connecting bands 51 and the fastening bands 71 ​​(described later) are lined up in the width direction V with the plate portion 61 sandwiched between them.

[0038] The plate portion 61 has a first plate surface 61a and a second plate surface 61b that are opposite to each other in the plate thickness direction. The plate portion 61 has a slit 62 in the center in the extension direction F. The slit 62 extends linearly in the width direction V from the second edge portion 612, of the first edge portion 611 and the second edge portion 612, from which the fastening band portion 71 extends. The slit 62 extends in the width direction V, which is a direction intersecting the extension direction F of the plate portion 61, and penetrates the plate portion 61 in the plate thickness direction.

[0039] A large number of deformation assist holes 63 are formed in the plate portion 61. The deformation assist holes 63 are elongated holes that penetrate the plate portion 61 in the plate thickness direction. The longitudinal direction of each deformation assist hole 63 extends in the extension direction F of the plate portion 61. A plurality of deformation assist holes 63 are arranged at equal intervals in the width direction V of the plate portion 61. A plurality of rows of deformation assist holes 63 arranged in the width direction V are provided in the extension direction F. In each row of deformation assist holes 63, the positions of the deformation assist holes 63 are shifted in the width direction V so that the deformation assist holes 63 are not adjacent to each other in the extension direction F. Note that no deformation assist holes 63 are formed on the imaginary line M that connects the connecting band portion 51 and the fastening band portion 71 in the width direction V in the plate portion 61.

[0040] 8, grooves 66 are formed on the second plate surface 61b of the plate portion 61, extending in the extension direction F along the longitudinal direction of each deformation assisting hole 63. The grooves 66 are recessed from the second plate surface 61b within the thickness of the plate portion 61. The introduction port 54 provided in the connecting band portion 51 is provided closer to the plate portion 61 than the maintaining portion 41.

[0041] <Fastening belt part> As shown in FIG. 1 , each fastening belt portion 71 extends in a belt-like shape from the second edge portion 612, which is one of the first edge portion 611 and second edge portion 612 of the plate portion 61 and does not extend from the connecting belt portion 51. The two fastening belt portions 71 extend from two locations on the plate portion 61 that are spaced apart in the extension direction F. The slit 62 is provided in the second edge portion 612, from which the fastening belt portion 71 extends, of the edges of the plate portion 61 that extend in the extension direction F. The slit 62 is located between adjacent fastening belt portions 71 in the extension direction F and extends in the width direction V.

[0042] Each fastening belt portion 71 extends in a belt-like shape with the plate portion 61 side as its base end. Each fastening belt portion 71 is flexible and deformable. As described above, the fastening belt portion 71 is arranged in a position aligned with the connecting belt portion 51 in the width direction V. Therefore, the two fastening belt portions 71 are spaced apart in the extension direction F of the plate portion 61. In detail, the two fastening belt portions 71 are arranged on both sides of the fixing portion 30 in the extension direction F.

[0043] The fastening belt portion 71 has a smooth surface 71a and an uneven surface 71b that are opposite to each other. The smooth surface 71a is a surface that continues to the first plate surface 61a of the plate portion 61. The uneven surface 71b is a surface that continues to the second plate surface 61b of the plate portion 61.

[0044] 4 and 5, the uneven surface 71b is formed with a plurality of belt engaging portions 72 arranged side by side in the extension direction of the fastening belt portion 71. That is, the fastening belt portion 71 has a plurality of belt engaging portions 72 arranged side by side in the extension direction from the plate portion 61. The belt engaging portions 72 are shaped so that their thickness decreases from the plate portion 61 side toward the tip of the fastening belt portion 71. The belt engaging portion 72 is formed with an inclined surface 72a that slopes toward the smooth surface 71a from the plate portion 61 side toward the tip of the fastening belt portion 71. The belt engaging portion 72 also has an engaging surface 72b that extends perpendicularly from the tip of the inclined surface 72a toward the smooth surface 71a of the fastening belt portion 71.

[0045] The width K1, which is the dimension in the short direction of the fastening belt 71, is smaller than the second opening width W2 of the retaining unit main body 42. In the fastening belt 71, the plate thickness T at the belt engaging portion 72 is smaller than the first opening width W1 of the retaining unit main body 42. Furthermore, the plate thickness T at the belt engaging portion 72 is larger than the minimum opening width when the operating piece 45 is not operated. Furthermore, the plate thickness T at the belt engaging portion 72 is smaller than the maximum opening width when the operating piece 45 is operated. Therefore, when the operating piece 45 is operated to set the internal space S to the maximum opening width, the fastening belt 71 can be moved within the retaining unit main body 42. Therefore, the retaining unit 41 has a retaining unit main body 42 that defines the internal space S through which the fastening belt 71 passes.

[0046] As shown in FIG. 1 , the fastening belt portion 71 is arranged in a position aligned with the connecting belt portion 51 in the width direction V. Therefore, the fastening belt portion 71 is arranged in a position aligned with the extending retaining portion 41 of the connecting belt portion 51 in the width direction V. The fastening belt portion 71 is insertable into the internal space S of the retaining portion 41 aligned in the width direction V. Furthermore, any of the retaining belt portion engaging portions 72 of the fastening belt portion 71 inserted into the internal space S of the retaining portion 41 can engage with the retaining portion engaging portion 46 of the retaining portion 41. Therefore, the retaining portion 41 has the retaining portion engaging portion 46 provided on the retaining portion main body 42, which engages with the retaining portion engaging portion 72. Therefore, the retaining portion 41 has the retaining portion main body 42 and the retaining portion engaging portion 46. Furthermore, the retaining portion engaging portion 46 of the retaining portion 41 can engage with the fastening belt portion 71 at different positions in the direction in which the fastening belt portion 71 extends from the plate portion 61. Furthermore, the retaining portion engaging portion 46 of the retaining portion 41 can engage with the fastening band portion 71 at a midpoint in the direction in which the fastening band portion 71 extends from the plate portion 61. In this way, pairs each consisting of a fastening band portion 71 and a retaining portion 41 that engages with the fastening band portion 71 are provided independently on both sides of the fixing portion 30 in the extension direction F of the plate portion 61. Therefore, the piping material holder 20 is provided with a plurality of pairs each consisting of a fastening band portion 71 and a retaining portion 41 that engages with the fastening band portion 71.

[0047] Furthermore, the plate thickness T of the fastening belt 71 at the belt engaging portion 72 is smaller than the width of the short-side opening of the introduction port 54. The width K1, which is the short-side dimension of the fastening belt 71, is smaller than the width of the long-side opening of the introduction port 54. Therefore, the fastening belt 71 can be inserted into the introduction port 54.

[0048] <Method of supporting piping materials using piping material holders> Next, a method for supporting the piping material 10 using the piping material holder 20 will be described. 6, the worker inserts the lower end of the hanging bolt 13 into the axial hole 30a and screws the hanging bolt 13 into the hexagonal nut 14 in the fixing portion main body 31 to fix the piping material holder 20 to the hanging bolt 13. Then, the piping material holder 20 is suspended from the ceiling surface by the hanging bolt 13.

[0049] When threading the lower end of the hanging bolt 13 into the hexagonal nut 14, the worker threads the hexagonal nut 14 onto the hanging bolt 13 until the lower end surface of the hanging bolt 13 protrudes downward from the second connecting wall portion 32b. The worker checks whether the lower end surface of the hanging bolt 13 protrudes downward from the second connecting wall portion 32b by visually checking from between the second connecting wall portion 32b and the third connecting wall portion 32c. The number of piping material holders 20 installed corresponds to the length of the piping material 10.

[0050] Next, as shown in Figure 7, the worker places the piping material 10 below the fixing portion 30 of the piping material holder 20, grasps the fastening belt portion 71, and moves the tip of the fastening belt portion 71 toward the associated maintaining portion 41.

[0051] Specifically, one of the two fastening bands 71 ​​is moved toward the retaining part 41. At this time, when the plate part 61 is divided in half with the slit 62 at the center, the side of the fastening band 71 that has been moved is easily pulled upward together with the fastening band 71. In other words, the side of the plate part 61 that has been moved on the side of the fastening band 71 is easily bent and deformed. Next, with one of the two fastening bands 71 ​​inserted into the internal space S of the retaining part main body 42, the other fastening band 71 is moved toward the retaining part 41 that is its partner. At this time, even if one of the fastening bands 71 ​​on the plate part 61 is in a bent and deformed state, by using the slit 62, it is easily pulled upward together with the fastening band 71.

[0052] The operator inserts the tip of each fastening strap 71 into the internal space S from the first end surface 421 side of the retaining unit main body 42 relative to the corresponding retaining unit 41. Then, the inclined surface 72a of the retaining unit engaging portion 72 pushes up the inclined surface 46b of the retaining unit engaging portion 46. This allows the fastening strap 71 to be fed into the internal space S. When the feeding of the fastening strap 71 into the internal space S is stopped, the engaging surface 46a of the retaining unit engaging portion 46 and the engaging surface 72b of the retaining unit engaging portion 72 face each other in the thickness direction Z. Therefore, even if the fastening strap 71 moves in the direction opposite to the feeding direction into the internal space S, the engaging surface 46a of the retaining unit engaging portion 46 and the engaging surface 72b of the retaining unit engaging portion 72 engage with each other. This engagement restricts the movement of the fastening strap 71 in the direction opposite to the feeding direction of the fastening strap 71 into the internal space S.

[0053] 8, an enclosed space 80 that surrounds the piping material 10 from the outer periphery of the covering material 12 is defined by the lower surface of the maintaining portion main body 42, the first band surface 51a of the connecting band portion 51, the first plate surface 61a of the plate portion 61, and the smooth surface 71a of the fastening band portion 71. When the enclosed space 80 is defined, the fastening band portion 71 extends in a band shape from the plate portion 61 in the width direction V and forms part of the portion that surrounds the piping material 10. The maintaining portion 41 is positioned next to the fastening band portion 71 in the width direction V, and when the holding portion 40 surrounds the piping material 10, the fastening band portion 71 engages with the maintaining portion 40 to maintain the state in which the holding portion 40 surrounds the piping material 10.

[0054] One end of the plate portion 61 in the width direction V is supported by the retaining portion 41 via the connecting band portion 51, and the other end of the plate portion 61 in the width direction V is supported by the retaining portion 41 via the fastening band portion 71. As a result, the connecting band portion 51 and the fastening band portion 71 are pulled upward above the plate portion 61. This causes the plate portion 61 to deform so as to be curved in an arc. Furthermore, since the plate portion 61 is positioned below the retaining portion 41 by the connecting band portion 51 and the fastening band portion 71, the plate portion 61 is positioned below the piping material 10.

[0055] The operator grasps the fastening belt portion 71 at a position closer to the tip end in the extension direction than the engagement point with the retaining portion 41 and pulls the fastening belt portion 71, or presses the fastening belt portion 71 at a position closer to the base end in the extension direction than the engagement point with the retaining portion 41. Then, the inclined surface 72a of the belt engaging portion 72 further pushes up the inclined surface 46b of the retaining portion engaging portion 46. As a result, the fastening belt portion 71 is sent further into the internal space S.

[0056] As shown in FIG. 9 , the worker inserts the tip of the fastening belt 71 into the introduction port 54. The worker then pulls or presses the fastening belt 71 to feed it toward the internal space S, adjusting the amount of fastening belt 71 fed into the internal space S so that the first plate surface 61a of the plate portion 61 is aligned with the outer peripheral surface of the covering material 12. At the same time, the worker pushes the tip of the fastening belt 71 into the introduction port 54 to feed the tip of the fastening belt 71 between the first belt surface 51a of the connecting belt 51 and the outer peripheral surface of the covering material 12 of the piping material 10. At this time, the worker narrows the enclosed space 80 by increasing the amount of fastening belt 71 fed into the internal space S. Therefore, the retaining portion engaging portion 46 can be positioned to allow the fastening belt 71 inserted into the internal space S to move in a direction that narrows the enclosed space 80 surrounding the piping material 10.

[0057] As the enclosed space 80 narrows, the fastening belt portion 71 side of the plate portion 61 is pulled up toward the retaining portion 41 and approaches the outer peripheral surface of the covering material 12. As a result, the curvature of the plate portion 61 decreases between the connecting belt portion 51 and the fastening belt portion 71. At this time, the worker gradually decreases the curvature so as not to damage the covering material 12 with the fastening belt portion 71. Therefore, the retaining portion 40 surrounds the piping material 10, and the size of the enclosed space 80 formed inside the retaining portion 40 can be changed to match the outer diameter of the piping material 10.

[0058] When the first plate surface 61a of the plate portion 61 is aligned with the outer peripheral surface of the dressing 12, feeding of the fastening strap portion 71 into the internal space S of the retainer body 42 is stopped. This causes the engagement surface 46a of the retainer engagement portion 46 to face the engagement surface 72b of the strap engagement portion 72. This facing causes the engagement surface 46a of the retainer engagement portion 46 to engage with the engagement surface 72b of the strap engagement portion 72. In other words, the retainer 41 engages with the fastening strap portion 71 at a midpoint in the extension direction. This engagement restricts movement of the fastening strap portion 71 in the direction opposite to the feeding direction of the fastening strap portion 71 into the internal space S. Therefore, the retainer engagement portion 46 can be positioned to restrict movement in the direction that widens the enclosed space 80 by engaging with the strap engagement portion 72.

[0059] As a result, the piping material 10 is maintained in a state in which it is surrounded by the holding portion 40, which is composed of the maintenance portion 41, the connecting band portion 51, the plate portion 61, and the fastening band portion 71. Then, with the piping material 10 surrounded by the holding portion 40, the piping material 10 is held by the piping material holder 20. Note that holding the piping material 10 by the piping material holder 20 means maintaining the state in which the piping material 10 is surrounded by the holding portion 40 and restricting the piping material 10 from slipping out in the radial direction from the holding portion 40, thereby preventing the piping material 10 from separating from the fixed portion 30. Therefore, holding the piping material 10 by the piping material holder 20 does not mean restricting the axial movement of the piping material 10 inside the holding portion 40 or the swinging of the piping material 10 within the enclosed space 80.

[0060] <Holding piping materials with different outer diameters> 9 and 11, there are multiple types of piping materials 10 with different thicknesses of the covering material 12. One of the multiple types of piping materials 10 is a large diameter piping material 111, and the others are small diameter piping materials 112 with an outer diameter smaller than that of the large diameter piping material 111.

[0061] As shown in FIG. 9, when a large-diameter piping material 111 is held by the holding portion 40, the retaining portion engaging portion 46 and the band portion engaging portion 72 engage at a large-diameter engaging position P1. Also, as shown in FIG. 11, when a small-diameter piping material 112 is held by the holding portion 40, the retaining portion engaging portion 46 and the band portion engaging portion 72 engage at a small-diameter engaging position P2. In terms of the position of the fastening band portion 71 in the direction of extension from the plate portion 61, the large-diameter engaging position P1 is located closer to the tip of the fastening band portion 71 than the small-diameter engaging position P2. Therefore, the retaining portion 41 can engage with the fastening band portion 71 at different positions in the direction of extension of the fastening band portion 71 from the plate portion 61. By changing the engagement position of the retaining portion 41 with the fastening band portion 71, the size of the holding portion 40 surrounding the piping material 10 can be changed.

[0062] The enclosed space 80 formed at the large diameter engagement position P1 is narrower than the enclosed space 80 formed at the small diameter engagement position P2. In other words, by surrounding the piping material 10, the holding portion 40 can change the size of the enclosed space 80 formed inside the holding portion 40 to match the outer diameter of the piping material 10. Therefore, even if there are large diameter piping materials 111 and small diameter piping materials 112 with different outer diameters, the piping material holder 20 can hold them. Therefore, by surrounding the piping material 10, the holding portion 40 can change the size of the enclosed space 80 formed inside the holding portion 40 to match the piping materials 10 with different outer diameters, and the entire extension direction F and entire width direction V of the plate portion 61 can be positioned below the surrounded piping material 10. In this case, the connecting band portion 51 and the fastening band portion 71 can form part of the portion surrounding the piping material 10.

[0063] When the small diameter piping material 112 is held by the holding portion 40 , the tip side of the fastening belt portion 71 is sandwiched between the first plate surface 61 a of the plate portion 61 and the outer peripheral surface of the covering material 12 . When releasing the holding of the piping material 10 by the holding portion 40, the worker operates the tip of the operating piece 45 to bring the first plate thickness surface 45a of the operating piece 45 closer to the upper first demarcating surface 41a. This maximizes the opening width between the maintaining portion engaging portion 46 and the lower first demarcating surface 41a, and disengages the engaging surface 46a of the maintaining portion engaging portion 46 from the engaging surface 72b of the band engaging portion 72. The worker moves the fastening band portion 71 in the direction opposite to the insertion direction into the internal space S, while keeping the first plate thickness surface 45a of the operating piece 45 closer to the upper first demarcating surface 41a. This expands the enclosed space 80, and the holding of the piping material 10 by the holding portion 40 is released.

[0064] <Operation of the embodiment> The operation of this embodiment will be described. As shown in FIGS. 9 and 10 , when the piping material 10 is held by the holding portion 40 of the piping material holder 20, the first plate surface 61a of the plate portion 61 is curved in an arc shape in the width direction V so as to follow the outer peripheral surface of the covering material 12. The longitudinal direction of the plate portion 61 extends in the longitudinal direction of the piping material 10 being held. Therefore, the plate portion 61 extends in the longitudinal direction of the piping material 10 and is deformable along the outer peripheral surface of the piping material 10 in the width direction V, which is perpendicular to the extension direction F of the plate portion 61. The plate portion 61 does not follow the entire circumferential direction of the piping material 10 being held, but follows a portion of the circumferential direction of the piping material 10 below the piping material 10. Therefore, the plate portion 61 has a first plate surface 61a that follows the outer peripheral surface of the covering material 12 and constitutes a portion of the circumferential direction of the holding portion 40 that surrounds the piping material 10.

[0065] The retaining portion 41 engages with the paired fastening band portion 71, and maintains the piping material 10 in a state where it is surrounded by the holding portion 40. The paired retaining portion 41 and fastening band portion 71 are independently provided on both sides of the fixing portion 30 in the extension direction F of the plate portion 61. In other words, the piping material 10 is provided with multiple pairs of retaining portions 41 and fastening band portions 71. The plate portion 61 is in surface contact with the covering material 12 from below. The two pairs of fastening band portions 71 and retaining portions 41 support the plate portion 61 from both sides in the extension direction F of the plate portion 61. Therefore, the piping material holder 20 supports the piping material 10 at a position between both ends of the piping material 10 in the longitudinal direction by surface contact. Therefore, the weight of the piping material 10 is distributed and supported by the plate portion 61.

[0066] <Effects of the embodiment> The effects of this embodiment will be described. (1) The fastening band portions 71 and the retaining portions 41 are each provided in multiple sets in the extension direction F of the plate portion 61. Therefore, compared to when the fastening band portions 71 and the retaining portions 41 are provided in only one location in the center of the extension direction F of the plate portion 61, for example, it is possible to make it less likely for the plate portion 61 to sag at both ends in the extension direction F. As a result, it is possible to prevent a reduction in the area that supports the piping material 10 by the plate portion 61, so that the weight of the piping material 10 can be distributed and supported. This makes it possible to prevent the covering material 12 of the piping material 10 from being crushed.

[0067] (2) The fastening belt portions 71 and the retaining portions 41 each engage with each other on both sides of the fixed portion 30. In other words, a pair consisting of a fastening belt portion 71 and a retaining portion 41 that engages with the fastening belt portion 71 is provided on both sides of the fixed portion 30. For example, by arranging multiple retaining portions 41 together on one side of the fixed portion 30, the fastening belt portions 71 may also be arranged together on one side of the fixed portion 30 so as to be able to engage with each retaining portion 41. In other words, a pair of the fastening belt portions 71 and the retaining portions 41 may be provided on one side of the fixed portion 30. Compared to this case, the retaining portions 40 can make it difficult for both ends of the plate portion 61 in the extension direction F to sag, thereby preventing a reduction in the area that receives the piping material 10 by the plate portion 61.

[0068] (3) The piping material holder 20 can change the size of the enclosed space 80 to match the outer diameter of the piping material 10 using the holding portion 40. Furthermore, when the size of the enclosed space 80 is changed, the plate portion 61 can be positioned below the piping material 10. Therefore, even if one type of piping material holder 20 holds piping materials 10 with different outer diameters, each piping material 10 can be stably supported from below. Furthermore, because the plate portion 61 can receive the covering material 12 from below, the plate portion 61 can distribute and support the weight of the piping material 10 compared to, for example, when the piping material 10 is held by a long, thin, strip-shaped member. This prevents the covering material 12 of the piping material 10 from being crushed.

[0069] (4) The plate portion 61 is formed with a slit 62. When one of the two fastening band portions 71 is engaged with the retaining portion 41, the slit 62 makes it easier to partially deform the plate portion 61 by moving the fastening band portion 71 toward the retaining portion 41. Therefore, compared to when the slit 62 is not present, it is easier to move the fastening band portion 71 toward the retaining portion 41. As a result, it becomes easier to hold the piping material 10 with the retaining portion 40.

[0070] (5) The holding portion 40 of the piping material holder 20 can maintain the size of the enclosed space 80 formed by the holding portion 40 through engagement between multiple sets of retaining portions 41 and the fastening band portion 71. Therefore, the state in which the piping material 10 is held by the holding portion 40 can be maintained at multiple points. Furthermore, by changing the engagement points between the retaining portions 41 and the fastening band portion 71, changes in the outer diameter of the piping material 10 can be easily accommodated.

[0071] (6) The piping material holder 20 can hold the piping material 10 by the holding portions 40 at two locations sandwiching the fixing portion 30. For example, even if the engagement between the fastening band portion 71 and the maintaining portion 41 is released at one of the engagement locations, the piping material 10 can still be held by the other holding portions 40.

[0072] (7) The piping material holder 20 can hold the piping material 10 at two locations sandwiching the fixing portion 30 using independent holding portions 40. For example, if the fastening band portion 71 is formed from a single wide band material, the size of the portion that holds the piping material 10 increases in the extension direction F, making it easier to prevent the holding portion 40 from tilting. However, in this case, the wider fastening band portion 71 makes it more difficult to bend the fastening band portion 71 to engage with the retaining portion 41. In contrast, by forming two fastening band portions 71 and engaging them with the retaining portion 41 at two locations, it is possible to prevent the retaining portion 40 from tilting and also to easily bend the fastening band portion 71 to engage with the retaining portion 41.

[0073] (8) When the tip end of the fastening belt portion 71 of the piping material holder 20 is inserted into the inlet 54, the tip end of the fastening belt portion 71 enters through the inlet 54 between the outer peripheral surface of the covering material 12 of the piping material 10 and the opposing outer peripheral surface of the piping material 10 at the holding portion 40. This prevents the tip end of the fastening belt portion 71 from being exposed to the outside of the holding portion 40. As a result, deterioration in the appearance of the structure in which the piping material 10 is held by the piping material holder 20 can be suppressed.

[0074] (9) A portion of the covering material 12 is compressed and deformed by the tip side of the fastening band portion 71 sandwiched between the plate portion 61 and the covering material 12. The recovery force of the covering material 12 from the compressive deformation urges the tip side of the fastening band portion 71 toward the plate portion 61. This allows the holding portion 40 to hold the piping material 10 in an appropriate manner.

[0075] (10) The locking portion 43 of the retaining portion 41 has a retaining portion engaging portion 46. The fastening band portion 71 has multiple band engaging portions 72 in the extension direction. When the inclined surface 72a of the fastening band portion 71 contacts the inclined surface 46b of the retaining portion engaging portion 46, the operating piece 45 is displaced, allowing the fastening band portion 71 inserted into the internal space S to move in a direction that narrows the enclosed space 80. Therefore, even if the fastening band portion 71 and the retaining portion 41 are engageable with each other, the enclosed space 80 can be narrowed. Furthermore, the engagement between the engagement surface 46a of the retaining portion engaging portion 46 and the engagement surface 72b of the fastening band portion 71 restricts the movement of the fastening band portion 71 in a direction that widens the enclosed space 80. This makes it easy to maintain the piping material 10 held by the retaining portion 40.

[0076] This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility. The connecting band portion 51 of the holding portion 40 does not necessarily have to have the inlet 54 formed therein.

[0077] The pair of fastening band portion 71 and maintaining portion 41 may be arranged together on one side of the fixing portion 30 in the extending direction F. The slits 62 of the plate portion 61 may be omitted, and the deformation assisting holes 63 may also be omitted.

[0078] The slit 62 may not be perpendicular to the extending direction F, but may extend obliquely from the second edge portion 612 . There may be three or more pairs of fastening band portions 71 and retention portions 41. There may be one pair of fastening band portions 71 and retention portions 41 on one side of the fixing portion 30, and two pairs of fastening band portions 71 and retention portions 41 on the other side.

[0079] The pairs of fastening band portions 71 and maintaining portions 41 do not have to be provided on both sides of the fixing portion 30. For example, multiple pairs of fastening band portions 71 and maintaining portions 41 may be provided on one side of the fixing portion 30.

[0080] The retaining portion 41 and the fastening belt portion 71 do not have to be engaged with each other. In this case, the retaining portion 41 does not have the locking portion 43. Furthermore, the fastening belt portion 71 does not have the belt engaging portion 72. In this case, a fixing member penetrating in the axial direction X is inserted through both the retaining portion main body 42 and the fastening belt portion 71 inserted into the internal space S to prevent the fastening belt portion 71 inserted into the internal space S from slipping out of the retaining portion 41. In this case, the fastening belt portion 71 has multiple through holes formed in the extension direction. The size of the enclosed space 80 can be changed by changing the positions of the through holes through which the fixing members are inserted.

[0081] The retaining portion 40 has a plate portion 61 extending from the retaining portion 41 and a fastening band portion 71 extending from the plate portion 61. In other words, the retaining portion 40 does not need to have the connecting band portion 51. In this case, the enclosed space 80 is formed by the retaining portion 41, the plate portion 61, and the fastening band portion 71.

[0082] The holding portion 40 may be formed by the plate portion 61 alone. The structure to which the fixing portion 30 is fixed may be a building wall. [Explanation of symbols]
